VEHICLE-SPRING.

Specification of Letters Patent.

Patented Apr. 3d, 191%..

Application filed June 30, 1916. Serial No. 106813.

"ing at- 'VVillard, in the-county of Torrance and State of New Mexico, have invented certain new and useful Improvements in Vehide-Springs, of which the following is a specification.

. This invention relates to a spring for automobile vehicles and has for its ob ect to pro-- vide a supplemental spring to be placed between the axle and the transverse spring of such vehicle to prevent thejside motion ofthe automobile body, to hold the front wheels steady and the car easier riding and easier steering. It also serves in a measure as a shock absorber and neutralizes the recoil due to shocks; it prevents the breaking of the spring tie boltand prevents the spring from slipping in the frame.

With these as the principal objects in view and others to be brought out in detail in the following description, the invention consists of the novel construction and arrangement of parts herein set forth and illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the front axle, hood and spring connections of a motor car with the improvement applied thereto, v i

Fig. 2 is a cross sectional view on an enlargcd scaleon the line 2'2 of Fig. 1,

Fig. 3 is a similar yiew on the line 3-3 of Fig. Land Jig. d is a perspective view of a modification.

Referring to the drawingby numerals 10 indicates'the front axle 0f-anaut0m0bile,11 the hood within which is the motor 12, the chassis supporting thehood and 13 the front spring; extending transversely of the car and par- "allel with the axle 10, said spring being secured to the chassis by clamps 14 and tothe axle by the usual links 15. The ahove-men- 'tioned parts are common to a well known type of automobile to which the present invention is particularly adapted and which is shovs n in Fig. 1 in place between the axle 10 and the spring 13. Preferably the supplcmcntal spring of the present invention is an elliptic spring 16, the upper and lower membcrs 17 and 18 respectively being formed of a single loaf pivotally connected at their inter-engaging endsby pins 19. The

lower-leaf l8 rests: upon a plat .20 and is 23 that overlie the leaf 18 and are Secured to the clamp 22 by nuts 24. v

The spring 16 and plate 20 are prevented from moving laterally or transversely on the axle 10 by the head'21 of the bolt 21 which is made conical and is seated in a similarly shaped recess or depression 10 made in the center of the axle as clearly shown in Figs. 1 and 2. By means of this conical head and the clamps 22, the supplemental. spring 16 is firmly secured to the axle and thoroughly protected or movement thereon due to the shocks which are imparted at times to the vehicle; The upper leaf 17 of the spring 16 is cenagainst any separation therefrom I trally secured to the transverse spring 13 and the chassis 12 of the Car by means of a central bolt 25 passing upwardly through these several parts and also by means of clamps 14 that extend under the upper leaf 17' to and above the top of the chassis where their reduced ends pass through transverse plates 26 and are secured by means of nuts 27 secured on the reduced end and against the plates 26. If desired instead of the U clampslet clamping means such as shown in Fig. 4 may be used which, it will be seen, comprises a rectangular plate 28 havincr upstanding legs 29 at each corner with. reduced screw threaded upper ends 30. This clamp is placed with the plate 28 against the leaf 1'?- of the spring; 16, the legs 29 of'which pass upwardly chassis 12 carrying the reduced threaded upper ends 30 above the same where the cross in front of and behind the plates 26 are placed over said ends and nuts clamp is further secured by means of the bolt'25 passing through a central hole 31 in the plate 28.

A car supported by an elliptic spring-such as 13 is greatly improved by means of the supplemental spring of the present invention as it renders the car more rigid, inc.-

proves the steering, making the same more reliable. causes the carto travel smoother, and all swaying movements due to the resiliency oi the semi-elliptic spring and the manner oi banging the body thereon i practically eliminated.

-" plane of the axle,

' adapted -to said upper member of the elliptic spring and What I claim is: The combination with an axle and the semi-elliptic spring of an automobile supported at its ends upon said axle and in line therewith by links mounted to swing in the of a supplemental elliptic s rlng between said axle and said semie liptie spring, means for securing the lower member of said elliptic spring to the axle, and means for securing the upper member of said elliptic spring and the semi-elliptic spring at their central points to the frame of the vehicle, said means comprising a plate bear upon the inner surface of JOSIAH N. UN DERWOOD. Witnesses:
